Oyster Offshore Wave Generator Is 2.5x Better Than Predecessor

This looks very cool. I wonder why we don't use more of these kinds of generators? Does anyone know their main drawback?

Oyster Offshore Wave Generator Is 2.5x Better Than Predecessor

Quote:

Power generation from waves continues to develop as Aquamarine Power has unveiled its new, second-generation Oyster 2 wave power generator. According to the company, "The new 800kW device will measure 26 metres by 16 metres and will deliver 250 per cent more power than the original Oyster 1 which was successfully deployed at the European Marine Energy Centre (EMEC) in Orkney last summer."

Wow !

I am liking the way / speed this technology is heading

The Oyster, at least last time I was talking to them, pumps high pressure water ashore. This requires directional drilling, siting onshore for a container sized water turbine to generator, and the ability to mount (ie drill) the hinge frame to the seabed. All the technologies are readily available, especially in places with an offshore oil/gas industry. In places like Oregon, the equipment can be pricey to bring for installation and maintenance.

A similar idea with using pressurized water instead of worrying about underwater electrical transmission lines is Carnegie Wave's CETO system. Instead of a hinge, it used to be a rubber float (hypalon or similar) tied to a pump on the sea-floor. It looks like there design is evolving to include a larger float (presumably to capture more wave energy).

Following the above link I found ,under projects , Canada , that they are currently in the process of developing a wave generation site in Ucluelet, about 100 miles from my house , in the next city/town.

side note:
On the other side of the Island (where i live) They are planning a Large wind generation Plant , mounted on the ocean floor between 2 island. Looks like the future energy is not so future after all.
Projects - Canada

I came across this webpage Voith | Wave power plants that describes a different way of using the Oceans waves that involves air pressure.

That looks VERY cool. I like that idea. Its so simple, and seems pretty maintenance free. Obviously, you're still dealing with salt water, so you have corrosion issues, but those can be designed around. I wonder how much power their test plant puts out.
